11 EXTERNAL PORTS

External PTT (Voice)
External PTT (Voice) is the transmission request port for voice channels. This port can be used for a transmission request
from a headset or external microphone.
The transceiver starts transmitting if the External PTT (Voice) port goes low level. The transceiver ends transmitting if the
External PTT (Voice) port goes high level. If the transceiver is on a data channel, the transceiver migrates to the lowest
numbered voice channel in the current zone and transmits.
Also, functions that are used for transmitting by using the External PTT (Voice) port can be configured using KPG-D1/ D1N.
(Refer to Functions When Sending by Using the External PTT (Voice), External PTT (Data), and Data
Note
The Data PTT, External PTT (Voice) and External PTT (Data) ports cannot be used at the same time.
External PTT (Data)
External PTT (Data) is the transmission request port for data communications.
The following are the 2 methods of use of External PTT (Data):
0
Using with the DTC port
In an LTR Trunking system, the port becomes the transmission request port in ARQ Mode.
The transceiver transmits by activating the External PTT (Data) port after activating the DTC port.
0
Using with Channel Select A to Channel Select D
This port functions as the transmit request port for external devices used for data communications. However, the
transceiver transmits on the currently selected channel without migrating to the Data Zone-channel in the same manner
as the Data PTT port.
The transceiver behaves as follows depending on the channel which has the External PTT (Data) port active:
Current Channel
Conventional Zone-channel (Analog)
Conventional Zone-Channel (NXDN/ P25/
DMR)
LTR Trunking Zone-Channel
P25 Trunking Zone-Channel
NXDN Trunking Zone-Channel
Also, functions that are used for transmitting by using the External PTT (Data) port can be configured using KPG-D1/ D1N.
(Refer to Functions When Sending by Using the External PTT (Voice), External PTT (Data), and Data
Note
The Data PTT, External PTT (Voice) and External PTT (Data) ports cannot be used at the same time.
